A linear vibration damping system (24) includes a piston (44) slideably disposed within a cylinder (42), a magneto-rheological fluid disposed within the cylinder (42), and a magnet (52) disposed in magnetic communication with the magneto-rheological fluid. A rotary vibration damping system (224) includes a cylinder (242) having a steering shaft (214) extending therethrough, a magneto-rheological fluid disposed between an inner surface of the cylinder (242) and an outer surface of the steering shaft (214), and a magnet (not shown) disposed in magnetic communication with the magneto-rheological fluid. In either system, the magnet is controllable to provide variable control of the magneto-rheological fluid. A method of damping vibrations in a motor vehicle includes disposing a magneto-rheological fluid at a source of vibration in the motor vehicle, controlling the magneto-rheological fluid to effectuate a structural change in the magneto-rheological fluid, and subjecting the magneto-rheological fluid to a vibration from the source of the vibration.
